When jettisonning fuel, the system logic allows the animation to show fuel jettisoning from the aircraft when the arm and jettison buttons are pressed even when an error has been made in entering the jettison gross weight such that it is higher than the current gross weight. Under such circumstances, the animation continues to play until the jettison button is pressed to off and guarded despite the fuel weight not decreasing (as it is below the jettison g.w.). Not a huge problem, and doubtless a little niche, but worth noting if it hasn't been picked up elsewhere .
